PGA900: Noise filters for ADC + calculations

Shafeeq Ramzan
Prodigy 20 points
Part Number: PGA900

With the PGA900 which one of the filters are responsible for filtering out noise within the Analog to digital conversion and how well does it filter out the noise i.e. What is the calculation for the output resolution after it has gone through this specific filter.

    Hi Shafeeq,

    The ENOB is specified in the datasheet under the P Analog-to-Digital converter section. The number can be improved by reducing the sampling output rate to increase the oversampling in the delta sigma modulator, and adjusting the PGAIN will also have an effect.

    Regards,
